Rough Leafcutter Ant
A medium-sized leafcutter ant with a distinctly rugose (wrinkled) exoskeleton covered in short spines. It builds relatively small underground nests in grasslands and forest edges. This species often harvests grasses rather than tree leaves for its fungal gardens.
Did You Know?
It is one of the few leafcutter species adapted to open grassland habitats, primarily harvesting grasses instead of tree leaves.
Willow Shoot Sawfly
A slender, dark stem sawfly whose larvae bore into the shoots of willow and rose. Females cause distinctive wilting of shoot tips by girdling the stem.
Did You Know?
The wilted, flagging shoot tips caused by this sawfly are often the most visible sign of its presence in wild rose thickets.
